The Tumbling of the Comet Nucleus

As the comet approaches the sun, during its passage through space it will rotate, spin, and tumble. The motion of the comet causes different sides to be exposed to the sun's warmth. The movies below show different sorts of nucleus shapes tuumbling through space as they approach the sun.
